Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Contract ticker ($BWH) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

DividendDistributor.process(uint256) (#314-338) has costly operations inside a loop:
- currentIndex ++ (#335)
Use a local variable to hold the loop computation result.

BabyWhiteHamster.swapThreshold (#446) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 1
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.7.4 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in BabyWhiteHamster.distributorDeposit(uint256,uint256) (#635-638):
- address(marketingFeeReceiver).call{gas: 30000,value: amount2}() (#637)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
